Time Stamping

The Timestamping or Digital Time Stamp is an online mechanism that offers technical evidence that a digital object (document, software, image, audio, video, log) exists and has not been modified. Generally this service is offered by a trusted third party, who issues verifiable timestamps. Adding reliable Timestamping to an electronic signature or code provides a digital seal of information integrity and a reliable date and time of when the operation took place. Recipients of documents and codes with a reliable timestamping can verify when the document or code was digitally or electronically signed, as well as verify that the document or code was not altered after.
